Group of answer choices 210 147 90 180 128A mountain region has a population of 5,000 mountain goats.

- A laboratory in British Columbia, the Kelatavicla lab, starts a mouse population where the frequency of the R allele is 0.5. You maintain this population for many years under the conditions found in column A. Given the information in the table (column A) and the information above it, predict what you think will happen to the frequency of the R allele. A) The frequency of the R allele will remain stable. B) The frequency of the R allele will increase. C) The frequency of the R allele will decrease.A researcher studies two types of fly populations. Population A have stubby bristles which are both shorter and blunter than population B. This is because the flies are homozygous for a certain allele for the stubble gene which affects bristle length. These flies are ebony coloured with black bodies. This is because they are homozygous for a certain allele for the ebony gene that affects body colour. Population B have longer and tapered bristles than population A and are not stubbly in appearance. This is due to them being homozygous for a different allele for the gene that affects bristle length to population A. These flys are not ebony coloured and have brown bodies. This is due to them being homozygous for the gene that affects body colour. The researcher crosses parental flys (P1) from population A with those from population B and counts the number of offspring that have stubble and non-stubble bristles, and the number of offspring that are ebony-coloured and non-ebony-coloured…A hypothetical population was found to have a genotype frequency of AA=20%, Aa=40%, aa=40%.
